Answer :
True. A diatomic ideal gas at pressure P and volume V is expanding to three times its initial volume under constant pressure.
Pressure Variations of a Diatomic Ideal Gas During Expansion
The pressure of the gas will remain constant as the volume expands, therefore the ideal gas law states that the product of pressure and volume will remain constant, meaning the pressure will decrease as the volume increases.
As the diatomic ideal gas expands to three times its initial volume, the pressure of the gas will remain constant due to the ideal gas law, which states that the product of pressure and volume must remain constant. As the volume of the gas increases, the pressure must decrease in order to maintain the constant product. Therefore, although the pressure remains constant, the volume of the gas will increase three-fold.
